We have create 6 patches based on latest
ffmpeg-master: 3282e31baaa77d161a4451c27ad0d45f78e1da0a
With these patches:
1. We modify HEVC plugin loading order, default to HW plugin,
since HEVC can be supported in SKL platform.
2. Move code in vaapi_allocator.c to ffmpeg_qsv.c, and re-use
hwaccel_context to enable video-memory transcoding.
3. Enabled VPP and fixed some issues.
4. Fixed some issues which is found by customer
ChaoX A Liu (6):
lavc/qsv(hevc): Change default plugin from hevc_sw to hevc_default,
which will load hevc_hw first, due to newly released MSDK.
lavf/vpp: Enable vpp filter, an Intel GPU accelerated scaler.
lavc/qsv: Enable hwaccel qsv_vidmem.
lavf/vpp: enable video memory accel for transcoding with vpp.
lavc/qsv: export symbols "ff_qsv_*" which will be used by vpp.
ffmpeg_qsv: set default hwaccel to qsv.
lavc/qsvdec: Reset decoder if MFX_ERR_UNDEFINED_BEHAVIOR is caught,
because this error may get decoder stuck.
lavc/qsv-lavc/vpp: Promote gpu_copy to be a selectable parameter.
GPU-copy is defaultly closed because it seems to be unstable.
